At our studio, we tend to create separate Overview pages for each episode of a TV series production; within each page are tabs for each stage of production-- Layout. Animation, Comp, etc -- schedule, assets, and others.
Say I've made some updates to the Lighting tab for episode 1 -- various detailed graphs, complicated color formatting rules, etc-- and I want to roll out that same format to the Lighting tab on all of the other episode pages. If those pages already exist, then I have to update it all manually.
It would be really handy to be able to copy that tab to another page, in the same way you can "Duplicate Page View" within a given page.
Maybe have a "Duplicate to..." function that lets you input the link of the project page that you want to copy that view to.
